ALUMINATOR® 1000 Aluminum IFR

Skin & Pontoon Internal Floating Roof


HMT’s ALUMINATOR® 1000 internal floating roof was developed in 1992 in response to market demand for a high quality, high strength aluminum skin and pontoon roof that can readily accommodate a mechanical shoe seal and not be subject to the same failure modes that sometimes plague conventional lightweight designs. The design of the HMT ALUMINATOR® 1000 was conceived and developed under the guidelines of API 650 Appendix H.

For a strong aluminum skin and pontoon internal floating roof that will stand the test of time even under heavy operating cycles, choose the ALUMINATOR® 1000.

    Key Benefits
    The ALUMINATOR® 1000 is the strongest skin and pontoon IFR on the market. The unique structural design is unmatched.
  • Handles turbulence / operating loads with ease — SIGMA STRUTTM girder for excellent torsional strength and excellent bending resistance, which means minimal deflection and likely no risk of permanent deformation; bi-directional girders means no dead-load or live-load stresses on pontoons
  • Excellent performance under heavy operating cycles — unique connection systems that transfers all landing/suspension loads to the girders, not to the pontoons
  • Heavy rim channel accommodates any seal system — extruded rim channel for extra strength can support a primary mechanical shoe seal and secondary seal without any modifications
  • Easy, fast installation — components easily carried through manways; no welding required
    Key Design Features
  • Bi-directional SIGMA STRUTTM girder system creates exceptional strength
  • Extruded bolting slots eliminate penetrations into vapor space
  • Extruded rim channel for additional structural support
  • 0.025” deck sheeting is 25% heavier than required by API 650
  • 10” diameter pontoons equipped with fully-threaded test port for vapor testing
  • Pontoons attached to girders using saddles and straps; no landing stresses on welds
  • Works with either leg-supported or suspended systems
  • Leg supports connect to the girder structure instead of the pontoons allowing for repeated flexing without the potential for pontoon end cap failure
